REFRIGEBATING SYSTEM AND REFRIGERATOR Application filed. August 21, 1930, Serial No.

The present invention relates to refrigerating systems and refrigerators.

One of the objects of the invention is to provide a refrigerating system in -which valves are completely eliminated.

Another object is to provide a refrigerator designed to operate with the novel refrigerating system.

Further objects will appear in the course of the detailed description now to be given with reference to the accompanying draw.-

ings, in which Fig. 1 is a section taken on line 11 of. Fig. 2 illustrating one constructive embodi-' ment of the invention;

Fig. 2 represents the same structure, in

plan, with the top closure removed;

Fig. 3 is an elevation of the refrigerating assembly in vertical position;

Fig. 4; shows the refrigerating assembly being heated in horizontal position.

Referring to the various figures of they drawings, there is shown a refrigerating system composed of a cylindrical boiler or gen erator 10, a cylindrical condenser or evaporator 2, a first tubular section 3 extending at 18 slightly into boiler 10 and communicating with the latter adjacent one end thereof, this section lying in a plane substantially at right angle to one passing through the axes of elements l0 and 2, a second tubular section substantially parallel to the axes of cylinders 2 and 10, a third tubular section 23 at right angles to section 13 and forming an angle of 30 with the plane passing through the axes of cylinders 2 and 10, said third section extending to but not into cylinder 2, a tube 8 extending axially through evaporator 2, and a man-hole or closure 9 for introducing liquid ammonia into the latter.

Elements 2 and 10 are assembled so that one of the ends of each lies in approximately the same mean plane so that both may rest on a common support when the assembly is in vertical position.

476,878, and in France September 28, 1929.

The herein above described assembly may be operated to produce a cooling effect inside any desired receptacle or enclosure in the following way:

The apparatus is placed horizontally in two tanks 4 and 5 (Fig. 4) filled with water. Tank 1 is then heated until the water therein boils, (100 C.) The ammonia dissolved in the absorbing solution contained in boiler 10' is driven off and after passing through tubular system 3, 13, 23 condenses under pressure in condenser-evaporator 2. The apparatus is then turned to vertical position (Fig. 3) and the boiler is cooled by immersion in cooling water recipient 5. .It will be noted that when no the apparatus is in horizontal position, portion 18 of tube 3 is above the solution in boiler 10 and that, in vertical position, said portion of tube 3 is immersed in the absorbing solution. The same holds true for the free ex- 55 tremity of tube 23. If it be desired to form a block of ice in a receptacle or mold of the type of element 5 (Fig. 1), condenser-evaporator 2 is immersed in the latter, ammonia will distill from cylinder 2 to cylinder 10 via tubes 3, 13, 23 and, in evaporating, congeal the water in receptacle 6, the distilled ammonia being absorbed by the solution contained in cylinder 10.

Fig. 1 shows the above described refrigcrating system applied to an ordinary household icebox 7, fitted with a top closure 14 and having a recess 17 in one wall thereof formed to receive tubular section 23, a plug or auxiliary cover 16 being provided to seal that part of recess 17 above tube 23, tubular section 13 being held in fixed relation to cylinder 10 by a strut 19. The assembly is completed by a metal basket 11, fitted with shelves 12 A and adapted to be lifted out of the icebox bodily. Gastors or knobs 15 permit easy 1 displacement of the entire assembly.

The dimensions of assembly 10, 2, 3, 13, 23 may be chosen so that the entire refrigerating system may be fitted inside'box 7 under cover 00 19, 2, 3, 13, 23 is entirely free 14-, thereby facilitating packing for transportation.

It will be noted that refrigerating system of valves of any kind. Danger from leakage is, therefore, completely eliminated, a valve'efi'ect being obtalned y displacing the entire assembly from horizontal to vertical position and vice versa.

What I claim is;:-

1. In a refrigerating assembly, a pair of closed elongated containers and a conduit extending from adjacent one end of one of said containers to a point adjacent the opposite end of the other of said containers, said conduit communicating with the upper portion of each of the containers when the latter are moved into horizontal position.

2. The method of producing ice comprising steps of providing a pair of containers communicating adjacent opposite extremities via a conduit, heating an ammoniasolution in oneof said. containers while the latter is horizontal so as to drive gaseous ammonia under pressure into the other container, wiereby the ammonia is liquefied, turning both containers into a vertical position, and placing water in contact with the container having liquid ammonia 4 therein, whereb evaporation of the latter will produce ice.

In testimony whereof I have signed this specification.
